A TTORNE Y To all w 7mm 2'17 may smweww residing at San Frank cc, in the county (if San Franciscs and Sm le of have invented new and useful impmvsmezits in Tire Censtructions, of which the fOiiG'WiBg is specification.

While I have shown the preferred form of my invention as now known to me, it will be understood that various changes might be made in the combination, construction and arrangement of parts by those skilled in the art, Without departing from the spirit of the invention, as claimed.

Having thus described my inventiom what I claim and desire to secure by Letters 11A tire comprising a body portion having/an annular air chamber formed adjacent the inner circumference thereof, and late-rally extending recesses formed in the body portion of the tire intermediate the air chamber and the tread, said recesses alternately extending from opposite sides of the tire in staggered relation to each other in a position to cause their inner ends to in tersect and laterally overlap, thereby formemmas ing a passageway circumferentially through the body portion of the tire and establishing a direct communication between all of .the

recesses.
